This morning I plugged in my 12inch PB and the green light started blinking on the charge indicator on the plug...I unplugged and plugged it back it and it persisted, but when I opened the computer the light went solid and then stayed solid...I'm confused, was it just not making a good connection? I have had problems with the plug because someone pulled the laptop off my desk at work this summer and the plug is now a little jacked up. Also, sometimes the light turns red, but when i wiggle the plug a little it goes back to orange. So basically...what the crap happened? And, if I buy a new charger, does it matter if i get the 65 or the 85 ?
